This function calculates the temporal offset between local solar time and UTC time zone. Calculation is based on geographic coordinates of each locality. Therefore, the function does not work when longitude coordinate is not provided.
mc_prep_solar_tz(data)myClim object see myClim-package
myClim object in the same format as input, with tz_offset filled in locality metadata
myClim assumes that the data are in UTC. To calculate temporal offset based on local solar time, this function requires
geographic coordinates (at least longitude) to be provided in locality metadata slot lon_wgs84 (in decimal degrees).
Geographic coordinates for each locality can be provided already during data reading, see mc_read_data(), or added
later with mc_prep_meta_locality() function.
TZ offset (in minutes) is calculated as longitude / 180 * 12 * 60.
